How to install the in-tree modules into the rootfs.

How to install the in-tree modules into the rootfs.

 Hi all,

step 1. Configure the kernel with some modules as "M".
step 2. Build the kernel.
step 3. After the building, there is a modules-*.tgz in the deploy/images directory.
My question is how to install it to the target rootfs. I assume it is "bitbake -f -c populate_sysroot core-image-minimal-dev', but i was wrong.

Thanks,
Biao

Each module ends up as a separate package (kernel-module-modulename); there is
also a kernel-modules package which installs all of them. In either case you
need to add those packages to the image. For information on how to do that,
see:

Cheers,
